I'm currently working with the band structure of graphene and graphene-like compounds.
α-Boron Nitride (hexagonal, single layer) has many interesting properties. I was wondering if the next period analogue, a hexagonal single-layered Aluminium Phosphide existed. Wikipedia lists this compound, but it seems to only be found with a multilayered sphalerite structure.
Does an allotrope of AlP exist (in a stable state at normal conditions) where the structure is similar to graphene or silicene? If not, why?
